WINDING-C ORE Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed January 30, 1907. Serial No. 354,900.

To all whom it may concern:

Be it known that I, JOHN HENRY GATELY, a citizen of the United States,residing at Bellows Falls, in the county of Windham and State ofVermont, have invented anew and useful Winding-Core, of which thefollowing is a specification.

This invention relates to winding cores for the support of roll goodsand is particularly designed for use in connection with paper makingmachines to have paper wound thereon as it comes from the machine.

The invention is more particularly designed as an improvement upon thatdisclosed in Patent No. 839,378, granted to me on Dec. 25, 1906, and itsobject is to simplify and chcapen the cost of the reinforces used inconnection with the core the same being of such size and construction asto be readily formed from pipes of standard sizes.

Heretofore cores of this character have been provided with reinforcingsleeves disposed therein and notched so as to be engaged by therotatable drive element, and such sleeves have been formed integral withother sleeves surrounding the core, and in order to produce devices ofthis character it has been necessary to use special mechanism therebygreatly increasing the cost thereof.

As has heretofore been stated the principal object of this invention isto provide reinforcing means which can be made from pipes of standardsizes and without the use of any special form of machinery.

A still further object is to provide reinforces which completelysurround the core so as to absolutely prevent the core from beingcrushed when in use.

With these and other objects in view the invention consists of certainnovel features of construction and combinations of parts which will behereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of theinvention.

In said drawings: Figure 1 is a perspective view of a portion of a coreembodying the present improvements; Fig. 2 is a longitudinal sectionthrough a portion thereof; and Fig. 3 is a perspective view of amodified form.

Referring to the figures by characters of reference, 1 designates thewinding core which may be made of paper or other suitable material andwhich has one end reduced annularly as shown at 2 so as to receive asleeve 3 preferably formed of a section of metal pipe of a standardsize, although it is to be understood that if preferred this sleeve canbe made of fiber or any suitable tough non-yielding material. Aninterior annular recess 4 is formed within the same end of the core 1and is preferably of the same proportions as the recess 4 and thisrecess is adapted to receive an inner sleeve 5 which is also preferablyformed of a section of metal pipe of a standard size, although it toomay be formed of fiber or other tough non-yielding material suitable forthe purposes intended. The two sleeves are held in place by means ofscrews, rivets or other suitable fastening devices 6 extendingtherethrough and into the core 1. After the sleeves have been positionedupon the core a notch 7 is cut into the end of the core and the sleeves3 and 5, said notch-being of sufiicient proportions to receive aprojection upon the drive element of the winding mechanism. It will beseen that by providing two separate sleeves 3 and 5 such as hereindescribed the core is reinforced both at the inner and outer edges ofthe notch 7 and there is no danger of the walls of the notch becomingtorn or enlarged as a result of their frictional contact with the driveelement. It will be understood of course that if preferred the innersleeve 5 may be dispensed with. i

It is sometimes desirable to leave the core end free of notches for thereception of the projection on the drive element and in this event theouter sleeve may be constructed and arranged as shown at 8 in Fig. 3. Byreferring to this figure it will be noted that said sleeve projectsbeyond the end of the core and the projecting portion thereof is formedwith a notch 9 of sufficient size to receive the projection on the driveelement. With this form of device the expense incident to the forma'tion of a notch in the sleeve or sleeves and core subsequent to theassemblage of the parts is eliminated, and

the outer sleeve can be notched before it is secured upon the core.

It will be noted that as the sleeves are formed of sections of pipes ofstandard sizes it is not necessary to make the sleeves of specialcastings. It will be further more noted that the sleeves are continuousand un broken throughout their extent so as to absolutely reinforce theend of the core against any pressure from any direction.

What is claimed is:

1. A tubular winding core having annular recesses in the inner and outerfaces thereof, a continuous interior sleeve of uniform thickness securedwithin the inner-recess, and a similar but larger sleeve secured Withinthe outer recesses, said sleeves being separate and the sleeves and oneend of the core having registering notches.

2. A tubular winding core having annular recesses in the inner and outerfaces thereof, separate pipe sections within the inner and outerrecesses, said sections and one end of the core having registeringnotches, and a fastening device extending through both sections and thecore for securing-the sections within the recesses.

3. A tublar winding core having annular recesses in the inner and outerfaces thereof, separate pipe sections within said recesses, one of saidsections having a notch in its outer edge, and a fastening deviceextending through the sections and the core to secure the sectionswithin the 10 recesses.

In testimony that I claim the foregoing as my own, I have hereto afiixedmy signature in the presence of two witnesses.

JOHN HENRY GATELY.
